Abstract:
The present invention relates to methods and apparatus for removing water and/or water-based compounds from organic liquids/fluids. In one embodiment, the present invention relates to methods and apparatus that utilize fibrous media that contains, is impregnated, or is formed from at least one super absorbent compound, where the fibrous media is formed from nanofibers.
Abstract:
A blind rivet includes a hollow rivet body having a longitudinally extending indented groove. The groove may be shaped to impart rivet setting characteristics that may be varied to provide desirable fastening characteristics for joints in a number of industries. The shape of the indentation on the rivet body may be varied to cause a portion of the rivet body to collapse and form a secondary head at a predetermined longitudinal location.
Abstract:
A system for delivering a desired mass of gas, including a chamber, a first valve controlling flow into the chamber, a second valve controlling flow out of the chamber, a pressure transducer connected to the chamber, an input device for providing a desired mass to be delivered, and a controller connected to the valves, the pressure transducer and the input device. The controller is programmed to receive the desired mass from the input device, close the second valve and open the first valve, receive chamber pressure measurements from the pressure transducer, and close the inlet valve when pressure within the chamber reaches a predetermined level. The controller is then programmed to wait a predetermined waiting period to allow the gas inside the chamber to approach a state of equilibrium, then open the outlet valve at time=t0, and close the outlet valve at time=t* when the mass of gas discharged equals the desired mass.

Abstract:
A vaporizer including an inlet for liquid and an outlet for gas, a gas valve controlling gas flow to the outlet of the vaporizer, and means for heating liquid flowing between the liquid inlet and the gas valve. The vaporizer also includes means for increasing a heat transfer rate of the liquid flowing between the liquid inlet and the gas valve, and for causing a pressure drop in the liquid so that a pressure of the liquid drops below a vapor transition pressure of the liquid upon reaching the gas valve. The pressure drop occurs under isothermal conditions, and the liquid is vaporized on demand only when the valve is opened. The means for increasing a heat transfer rate and for causing a pressure drop can be a plug of porous media.

Abstract:
A vehicle entertainment and accessory control system (10) is disclosed. The control system (10) provides a plurality of touchscreens (12,14,16) that present user interfaces (38,62) concurrently with video windows (40,64). The user interfaces (38,62) enable users to control various entertainment components, such as a video display (22) and a speaker (24), as well as other vehicle accessories, such as an intercom (28). The entertainment components are controlled via a universal infrared controller (20). A master touchscreen (12) enables a user to control access to the system (10) via a plurality of passenger touchscreens (14,16) by disabling or limiting the use of the passenger touchscreens (14,16).
Abstract:
A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.
Abstract:
A medical implant and method for implantation of the same. One embodiment is an implant for use in the treatment of stress urinary incontinence that includes an implantable, elongated tape having a multiplicity of openings formed through the thickness thereof, the tape having a first end region and a second end region longitudinally opposite the first end region, and first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively. Each bio-compatible fixation element has a tissue adherence property greater than that of the tape.
Abstract:
A flowmeter has a variable area, vertically-oriented duct through which flows fluid whose flow rate is to be determined. A float in the duct assumes a position in the duct that depends on the flow rate of fluid in the duct. A window is located at an end of the duct in alignment with a longitudinal axis of the duct. A transducer unit projects a light beam through the window and along the axis toward the float. The transducer includes a light sensor that detects light returned by the float by reflection or some other mechanism to the transducer unit. The intensity or other characteristic of the returned light indicates the position of the float in the duct, from which the fluid flow rate may be determined.
